8 Claims.

The invention relates to railway freight cars preferably of the house orrooted type and has for its object to provide means for protecting thewooden floors now in general use in such type of equipment, which meanswill not interfere with the securing of blocking to the wooden flooring,to which the lading is secured.

Another object of the invention is to provide a metallic protectingsheathing which rests upon the wooden flooringof the railway car and isprovided with apertures or perforations so that the car lading may benailed or otherwise secured to the flooring through the apertures.

Another object is to shape the apertures so that they are long enough toprovide a relatively large area for nailing and are relatively narrow sothat the wheels of loading trucks or shoes of workmen will not getcaught therein.

Another object is to form the sides of the elongated apertures withstiflening flanges to prevent the edges of the apertures from curling upand also to stiffen the sheathing as a whole against buckling. Thesestiflening flanges may project downwardly and be imbedded in the woodenflooring to help hold the sheathing in place or they may projectupwardly so as to provide means to prevent slipping. I prefer to projectsome flanges upwardly and some downwardly.

The apertures are preferably positioned in staggered relationship withthe end portions thereof overlapping each other so that the severalflanges of the several apertures cooperate to reinforce and stiffen thesheathing.

Another object is to shape the elongated apertures with non-parallelsides to provide relatively narrow end portions and a relatively widemiddle portion so that the edge of the plate around the apertures willhave a tendency to lie flat instead of bending up.

Another object of the invention is'to provide a metallic sheathingwhereinsome of the elongated apertures are positioned with their longdimension parallel to the short dimension of some of the other aperturesand to provide said 5 elongated apertures with flanges along their sideswhich are substantially parallel with each other for use in driving theflanges into the wooden floor.

' In the drawings:

Fig. 1 shows a floor plan of part of a railway box car equipped with myfloor protection.

Fig. 2 is a section on line 2-2 of Fig. 1. Fig. 3 is a. section on line3-3 of Fig. 1. Figs. 4 to 11 inclusive show various forms of aperturesin the metallic sheathing area of opening is provided for nailing In theform or my invention illustrated, the usual parts of thecar are shown,such as the center sills 2, side sill 3, door posts 4 and woodenflooring 6. The wooden floor 5 usually comprises a plurality of woodenshiplapped or 5 tongued and grooved boards extending laterally of thecar which are secured directly or indirectly to the center sills 2, sidesill 3 and floor stringers (if used).

My metallic sheathing I rests on the top of the 10 wooden floor 5 and ispreferably secured thereto by bolts, screws or nails.

I preferably provide an elongated substantially diamond shaped apertureiii-l l-l2-l3--il wherein the middle thereof is relative wide 5 with endportions tapering to points or r unded terminals. By this arrangement avery l large but at the same time only a relatively small thing maypenetrate the aperture. This shape of aperture 20 presents substantiallyconvex sides which do not have a tendency to kick up. v

The sides of the aperture, or parts thereof, are

' provided with stiifening flanges which may project upwardly to provideanti-slipping means or 5 may project downwardly and be imbedded in thewooden floor to hold the sheathing down and from moving parallel to thetop of the wooden floor. These flanges are preferably positionedparallel to the grain of the wood so that they 30 may be easily driveninto the wooden flooring.

The flanges of some of the apertures may project upwardly and theflanges of other apertures may project downwardly for the purposesspecifled, and in fact, the flanges of a single aperture 35 may projectupwardly and downwardly and come within the scope of the invention.

Figs. 4 and 5 show my preferred form of aperture, wherein Fig. 5 is asection on line 5-5 of Fig. 4. The elongated aperture in has a rela- 40tively wide middle part with parallel sides is with the sides i6 of theend portions merging into pointed ends iii. .The parallel side portionsii are provided with pointed or rounded flanges 20. 45

- Figs. 6 and 7 show a modified form of aperture (Ii) wherein Fig. 7 isa section on line 1-1 of Fig. 6. The sides of the aperture are providedwith flanges 22 following the contour of the side edges of the apertureand merging (24) 50 into the sheathing adjacent the opposite ends 26 ofthe aperture. This aperture is formed by slitting the plate along line1-1 from 30 ton and forming the flanges of the material between thesides oi. the aperture and this slit. 66

Figs. '7 and 8 show a modiflcation wherein Fig. 9 is a section on line99 of Fig. 8. This elongated aperture I2 is curved with the convex edge34 thereof formed with a flange 36 extending.

may be positioned in parallel rows with adjacentapertures positionednormal to each other for overlapping relationship, as shown to the leftin Fig. 1.

Figs. 10 and 11 show a modification wherein Fig. 11 is a section on lineHII of Fig. 10. The preferably elongated apertures are substantiallyrectangular in shape and are positioned with the longitudinal axes ofone group thereof substantially normal to the axes of another groupthereof, as shown on the left side of Fig. 1. The apertures l3 of one ofthese groups are provided with flanges 40 at the long sides 01' therectangle and the apertures of the other group are provided with flanges4| at the short sides of the rectangleso that the flanges 40-41 of allof the apertures are substantially parallel with each other. Themetallic sheathing I is preferably laid upon the wooden floor 5 with theflanges extending substantially parallel with the grain of the wood sothat they may be easily driven into the wood. Y 4

In Figs. 9 and 10, I have shown saw tooth flanges 40 which whenprojecting upwardly form an eiilcient non-skid construction and whenprojecting downwardly can be easily driven into the wood.

The accompanying drawings illustrate the preferred form of theinvention. though it is to be understood that the invention is notlimited to the exact details of construction shown and described, as itis obvious that various modiflcations thereof, within the scope of theclaims, will occur to persons skilled in the art.
